Abstract

Small black beans (SBB) were germinated up to 72 h at 23oC, and 48 h germinated SBBs having the highest isoflavone content were chosen for noodle preparation. Some of the germinated SBB were treated by 20 min boiling (B) but some were not boiled (NB). For noodles, the germinated SBB flour replaced 15% or 20% of wheat flour, so five kinds of noodles were prepared and tested: control, 15B, 15NB, 20B, and 20NB. Higher amount of bean flour resulted in significant decrease of L* and increase of b* values in noodle. After 20 min cooking, the noodles containing germinated SBB flour showed less soluble sugar content in cooked water than control, and the lowest value was observed in 15B. For textural properties, the addition of SBB flour lowered hardness and adhesiveness of noodle, but increased chewiness than control. In sensory tests, the most acceptable sample was 15B because of developed texture and better appearance which seem to be good for health.
